Legacy of Leadership

From the invention of non-invasive radiosurgery to the widespread
recognition of Gamma Knife
®
as the gold standard, Elekta continues to
innovate technology to improve patients’ lives.

Clinical Advancement Comes From Asking

“What’s Best for the Patient?”

The question asked by Elekta founder, the late professor Lars Leksell, a neurosurgeon
at Sweden’s Karolinska University Hospital, was, “What is best for the patient?”
He believed in a better, safer way to treat people with brain disorders and cancer.
Instead of performing major surgery, he worked with colleagues to develop a new field
of medicine — fighting neurological disorders with precisely targeted doses of radiation. With this new
treatment, patients could avoid open surgery and preserve healthy tissue.

Largest Clinical Evidence

More than 2800 peer-reviewed
publications describe the use of Gamma Knife.

Patients Treated

More than 75,000 patients treated
worldwide yearly with Gamma Knife.

2013

KLAS Award

Gamma Knife receives top ranking
for the fourth consecutive year
from an independent medical
device-research company.

2009

Since 2009 over 280,000
treated
for Brain Metastases

Brain Metastases is the most common
condition treated with Gamma Knife.

Perfexion®

Elekta introduces a breakthrough technology for delivering radiation with extremely high precision and accuracy. Perfexion makes treating complex and multiple targets more efficient.

1999

Automatic Positioning

Elekta introduces the first robotic patient positioning system in Gamma Knife. The treatment becomes faster and more automated.

First patient treated in U.S.

The first patient treated in U.S.
was at the University of Pittsburgh
Medical Center. Today, Gamma Knife
is considered the gold standard
radiosurgery system, with leading
medical centers around the world
preferring it as an alternative to
traditional surgery for the treatment of
complex, difficult brain conditions.

First systems
installed outside
of Sweden

Gamma Knife systems installed in UK and Argentina.

Gamma Knife

The first Gamma Knife
radiosurgery system
prototype was installed in
Stockholm, Sweden.

1968

1951

Developed the concept
of Radiosurgery

Leksell and the physicist and
radiobiologist Borje Larsson
develop the concept of
radiosurgery for the treatment of
cranial disorders.

Stereotactic

In 1949, Professor Lars Leksell developed his arc centered stereotactic frame based on Cartesian coordinate system.

1949

“Tools used by the surgeon must be adapted
to the task and where the human brain is
concerned, no tool can be too refined.”

— Elekta Founder, Professor Lars Leksell

Pioneer
Lars Leksell

1907-1986

When Professor Lars Leksell
invented the stereotactic frame in
1949, he probably didn’t expect his
small, family-run company to become
the world leading developer and
manufacturer of stereotactic solutions.

Today, Professor Leksell’s vision
of non-invasive neurosurgery
has become the gold standard with
Leksell Gamma Knife.

Fraction: Part of the total radiation dose, delivered at a daily treatment.

Intensity Modulated Radiation Therapy (IMRT): Intensity modulated radiation therapy of cancer, where instead of being treated with a single, large, uniform beam, the patient is treated with many very small beams; each of which can have a different intensity.

Linear accelerator: Equipment for generating and directing ionizing radiation for treatment of cancer.

Magnetic resonance imaging (MRI): Technology used to visualize and differentiate organs and anatomical structures inside the body. It uses non-ionizing radiation and is thus harmless to the patient.
